Supplier of steel ruler calibration device

Product Introduction

Steel ruler calibration device - length measuring instrument

The length measuring instrument of PTTC-GZ2 steel ruler calibration device is designed and developed by Henan Putian Tongchuang Metrology Co., Ltd. according to the current JJG1-1999 steel ruler calibration regulations. This calibration device is used to calibrate steel rulers and is a precision engraved metal ruler with a reading magnifying glass and a thermometer. Commonly used to check the distance between contour points, control points, and coordinate network points, it is specified in the national leveling measurement standards as a standard ruler for calibrating leveling scales. High precision, high stability, high clarity, precise and consistent engraving line width and spacing.

Product Features
High precision, high stability, high clarity, precise and consistent engraving line width and spacing;
The difference shows a linear curve of rise and fall, without sudden jumps or occasional errors in peaks and valleys;
The engraved line is vertical standard, the ruler has good rigidity, low deformation rate, and good flatness.

Product Usage
The PTTC-GZ2 steel ruler calibration device is commonly used as a length measuring instrument to check the distance between contour points, control points, and coordinate network points. It is specified in the national leveling measurement specifications as a standard ruler for calibrating leveling scales. Other professional departments are also widely used for measuring and measuring straight-line distances and markings.
